AI Technical Summary
The existing tobacco fertilizer measuring cylinder has a fixed volume, which makes it difficult to observe the liquid level, resulting in inaccurate measurements, and the measurements are also inaccurate when tilted.
An adjustable measuring cylinder for tobacco fertilization has been designed, comprising an adjustment component and a connecting component. The adjustment component achieves capacity adjustment through a sliding plug and a threaded rod, and the connecting component keeps the measuring cylinder horizontal through a bent tube.
It enables accurate observation of liquid volume at any angle and keeps the measuring cylinder horizontal when tilted, ensuring the precision and accuracy of fertilizer application.
